linux/sound/soc/codecs/rt5651.c
Linus Torvalds 3acbd2de6b sound updates for 4.20 
There have been little changes in ALSA core stuff, but ASoC core still
 kept rolling for the continued restructuring.  The rest are lots of
 small driver-specific changes and some minor API updates.
 Here are highlights:
 
 General:
 - Appropriate fall-through annotations everywhere
 - Some code cleanup in memalloc code, handling non-cacahed pages more
   commonly in the helper
 - Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
 
 Drivers:
 - More HD-audio CA0132 codec improvement for supporting other Creative
   boards
 - Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
   give move support of existing HD-audio devices with DSP
 - A few device-specific HD-audio quirks as usual
 - New quirk for RME CC devices and correction for B&W PX for USB-audio
 - FireWire: code refactoring including devres usages
 
 ASoC Core:
 - Continued componentization works; it's almost done!
 - A bunch of new for_each_foo macros
 - Cleanups and fixes in DAPM code
 
 ASoC Drivers:
 - MCLK support for several different devices, including CS42L51, STM32
   SAI, and MAX98373
 - Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
   MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
   TI PCM3060
